-4°F is the minimum recommended temperature setting of the freezer compartment for normal ice production. If the freezer temperature is set at a warmer temperature, then the ice will produce at a slower rate.

If the doors of the refrigerator are opened often, the cold air will escape which will prevent the unit from maintaining the set temperature. Lowering the temperature can help, as well as not opening the doors as frequently.

You may also try using the ‘Express Freeze’ or ‘Ice Plus’ feature. This option will operate the compressor continuously for three hours. With this option, the cold air in the freezer compartment is increased as is ice production. Before activating this option, set the freezer temperature to 0°F or colder.
